I just wanted to confirm that Laszlo has reached us with this particular issue. Back with the previous versions there was the Save 3D Window as... command that could result the cut object. Starting from ArchiCAD 17 we have now the Save selection As... option, which helps in many cases, but not in this one.
We are checking at the moment how we could implement the old way with the new set of available commands. Until then, please use the SEO trick.
